Patented Oct. 30, 1934 PATENT lOFfTFlIfClE STATES .This Ainventionrelates to 4suction rolls, and more particularly to `an arrangement ofthe shower pipes of rsuction rolls.

Suction rolls are substantially universally proalfvided Withishower`pipes Adirecting sprays of liuid 4against the inner surface of theshell immediv`atelyrin advance of that edge of the vsuction box `,first'engaged by agiven portion of the shell in 'Sits rotation. lParticles ofnbre vand felt passing "d through the openings of the shell collect uponthe pipe 'tending to clog the `openings and, fur- "therr'norapar'ticlesof foreign matterin the water delivered through the pipe vgather intheopenlings' and tend to clog the same so that the shower {3,3'15pipeifhas ltolbe removed Vand cleaned. This must Abe `done whenever theshower fails to operate properly, for this lshower in addition tocleansing the roll lubricates'the inner surface of the roll '-so -thatit may not have too great a frictional jzo engagement with the packingsof the suction box. As at present c'zonstructed,l such devices require*dismantling of -the roll in order that they "may fbe removed forcleaning, and an important 'object of the present 'invention is theprovision w25 of 'a shower pipe varrangement permitting the .pipe to beremoved for cleaning without dismantling the roll.

A further object 'of the inventionis the provision inra device of `thischaracter iof anarrangement such that the shower pipe can Abe `removedwithout breakingany actual `pipe connections and simply disengaging theshower pipe from a rslip joint through which its connection with thewater supply is provided. n.35 f A further object lof the invention isthe provision of'a shower pipe so constructed that it Amay be veri7readily cleaned andfmay be readily inserted 'into position in the roll.These and other objects I attain by the conist`ruction shown in the`drawings wherein, for

lthe purpose of illustration Ih'ave shown a preferred embodiment of myinvention and wherein: Fig. `1 is a longitudinal sectional View througha 'suctionroll equipped With a spray pipe in ac- Acordance with myinvention;

.Referring now more -particularlyto the drawings, the numeral 10generally designatesa `ro- 60 tating shell of a suction roll; 11, endv'heads therefor, having hollow trunnions 12 mounted in suitablebearings 13, one of 4theseend heads being `connected `as usual to thedrive mechanism indicated at 14 through its trunnion. Within the 65shell isarranged the -suction -box 15, thisbox being at `present shownas of that -type illustrated in the prior patent vto -EdwardT. `Streetunder date of June 30, 1931, No. 1,812,812, for

`Suction rolls. The ends of this suction box lhave trunnions 16 and 17which are mounted and guided in the trunnions 12 of the shell,

In accordance With my invention, the trunnion Y17, which is projectedentirely through the associated shell trunnion `in order that it may beconnected with adjusting means generally designated at 18, has arrangedtherein a longitudi- -a substantially tangentially-extending vconduit 20the upper end of which is equipped with 85 a tting more particularlyshown in Fig. 5. This fitting comprises a tubular chamber 21 the bore ofwhich is tapered adjacent one end as indicated at 22. The side wall ofthe chamber has an opening therethrough at such tapered portion asindicated at 23 for communication with the conduit 20. The opposite endof the chamber 21 is threaded, or otherwise adapted at 24, forconvenient attachment of a head 25. InWardly of this connection, a slot26 is formed in the 95 inner surface of the chamber for a purposepresently to appear.

The axial bore of the chamber 21 is `directed. along one side of thesuction box; i. e., that side thereof bearing the packing 27 which isrst en- 100 gaged by any given portion of the shell l0 during itsrotation. Secured to the suction box are a plurality of brackets 28 eachhaving an opening 29 coaxial with the bore of chamber 21. The spraytubecomprises a tubular body 30 `enclosed 105 at its opposite ends asindicated at 31 and 32, the closure 32 comprising a plug secured to thetube by a pin 33 which projects beyond the outer surface of the tube andengages in the slot 26 of chamber 21 in order that the openings of thetube l `lil 'zie may be properly directed. The closure 31 comprises atapered plug threaded into the end of the tube and apertured at 34 topermit the insertion of a tool whereby this closure may be removed. Pin33 may have a loose fit so that closure 32 may be readily removedthrough medium of a handhold 35 connected therewith, which handholdernbodies a portion rotatable in the head and has threaded engagementWith the closure 32. The exterior surface of the tube, adjacent closure32, has sweated or otherwise secured thereto or pro, vided thereon atapered conical surface 36 adapted to fit the tapered bore of thechamber and through the tube and this tapered vsurface an opening 37 isformed which aligns With the opening 23 ofthe chamber when. the tube isin position therein.y

Since the handhold is rotatably engaged by the head 25, it will beobvious that this Vhead'may be rotated to disengage it from the chamber,the head being provided with angular shoulders 38 'for engagement by aWrench. The head, during rotation to disengage .the same `from thechamber 21, engages a shoulder 35a on handhold 35, breaking the taperjoint connection so that by anaxial pull` the unit constituting thespray pipe may be Withdrawn from the chamber. The adjacent -head 11 ofthe shell has an opening 39 formed 'therein which may be aligned withthe tube and 'through which the tube may be withdrawn and reinserted,and the head 25 is readily accessible ythrough such opening fordisengagement by means of asocket Wrench. When the tube is Withdrawn,the closures of the opposite ends thereof may be In reinserting thetube, the closure 3l assists in engaging the tube in the openings -ofthe brackets.
